Description

  In this invention, when fixing various members to the inner wall surface of a building, the mounting of the plate material to the structural material used to fix and arrange the plate material as a reinforcing base for mounting the member between the pillars as the structural material Related to brackets.

  For example, in a building wall where the inner wall is finished using an inner wall surface constituent material such as gypsum board, when attaching various members such as handrails to the inner wall surface, it is not possible to secure sufficient member mounting strength with the wall surface constituent material alone. Further, it is necessary to arrange a plate material as a reinforcing base on the back surface side of the wall surface constituting material, and it is necessary to fix such a plate material to a pillar constituting the wall with a mounting bracket.

  For example, Patent Documents 1 and 2 can be cited as conventional metal fittings that can be used for fixing the above-described reinforcing base plate to the column.

  First, the metal fitting of patent document 1 is a connection metal fitting of the heat insulating material panel given to the inner wall of a building, and it overlaps with the front edge of the side plate interposed between the frame materials of adjacent heat insulating material panels, and the front surface of one frame material. A surface abutting piece that is bent to the other side, a folding piece that is foldable with respect to the side plate so as to be able to be superimposed on the front surface of the other frame member, and a rear edge of the side plate so as to overlap the rear surface of the other frame member It has a structure in which a back contact piece that is bent is provided.

  To connect the insulation panel with the above-mentioned connecting bracket, attach the connecting bracket by overlapping the side plate on the side of one frame member positioned on both sides and fixing it with screws, and then fit it between the frame column. The other heat insulating material panel is supported by the back abutting piece, then the bent piece is bent so as to overlap the front surface of the other frame member, and the screw is screwed into the other frame member from the screw hole provided in this bent piece. Thus, the heat insulating panels are connected to each other.

  Such a connection fitting can be used for fixing the plate material between the columns as it is if the one heat insulating material panel is a column and the other heat insulating material panel is a plate material.

  Next, the metal fitting of patent document 2 is a support metal fitting which attaches the board | plate material for buildings between both beam members, and is used for the beam material which overlaps the front surface of a beam material on the front edge of the side plate interposed between a beam material and a plate material. The front plate and the front plate for the plate material that overlaps the front surface of the plate material are bent and provided so that the rear plate for the plate material positioned on the rear surface of the side plate protrudes on the same side as the front plate for the beam material. The support brackets are attached to both sides of the plate by sandwiching the sides of the plate between the front and rear plates of the beam, and the plate is fitted between the beams to secure the beam front plate. By stacking on the material, it is designed to attach the plate material between the beam materials, and for mounting the plate material between the columns, such support brackets can be used as they are by using the both side beam materials in Patent Document 2 as columns. It will be possible.

  By the way, the connection metal fitting of patent document 1 requires the operation | work of having to bend a bending piece in a construction site, and when it is applied to fixation of the board | plate material with respect to a column while the bending requires extra work, The fixing force of the plate material depends only on the fastening force between the bent piece and the plate material by the screw screwed into the plate material from the bent piece.

  That is, the bent piece is bent with respect to the side plate so that the plate material is sandwiched between the back contact piece and the back contact piece. In such a case, there is a case where a gap is generated between the plate and the back contact piece that is drawn to the bent piece side by screws, and the fixing of the plate is bent. It becomes only the fastening part by the screw of a piece and board material.

  As described above, in fixing the plate material, the clamping force of the plate material by the bent piece and the back contact piece cannot be utilized for the fixing strength, and the load acting on the screw by the plate material is supported by the bent piece of the screw. Therefore, the plate fixing part of the screw is weak against the shearing force, and the fixing strength of the plate that is the base for reinforcement when attaching a handrail to the wall surface is sufficient. The problem arises that it cannot be secured.

  Moreover, since the support metal fitting shown in Patent Document 2 has a mounting structure in which a plate material is simply fitted between beam members, even if there is no problem in mounting the plate material in a horizontal state, When applied to the installation of a plate on a vertical surface, not only can the plate not be stably and vertically supported, but also cannot be fixed to the pillar, so the plate that will be the foundation for reinforcement when attaching handrails, etc. It is unsuitable for strength as a fixing.

  Accordingly, the problem of the present invention is that the plate material can be clamped from the front surface and the back surface by screwing in to make use of the fixing force, and by supporting the screw through which the plate material is penetrated in two places in the length direction, An object of the present invention is to provide a mounting bracket for a plate material to a structural material that can improve the strength against the shearing force of a fixed portion.

  In order to solve the above-mentioned problems, the invention of claim 1 is a mounting bracket for screwing and fixing a plate material to a structural material, and is attached to a front edge of a side plate interposed between the structural material and the plate material. A front plate for a structural material that has a screw hole for a screw to be screwed into the structural material and is fixed to the front surface of the structural material by the screw; The front plate for plate material fixed in a state where it is stacked on is provided so as to protrude toward the opposite side, and the rear plate for plate material positioned on the rear surface of the side plate on the rear edge of the side plate is the same as the front plate for plate material The rear plate for plate material is formed so as to face at least part of the front plate for the plate material and to be shorter with respect to the vertical dimension of the side plate. One end edge located on the top and bottom of the plate is used as a screw engagement edge. The positional relationship between the joint edge and the screw hole provided in the front plate for plate material is screwed into the plate material from the screw hole of the front plate for plate material, and the screw thread of the plate fixing screw that penetrates through this engages with the screw engagement edge. It is set to do.

  According to a second aspect of the present invention, in the positional relationship between the screw engagement edge of the plate rear plate and the screw hole provided in the plate front plate, with respect to the axial extension line of the screw hole provided in the plate front plate. The screw engagement edge of the rear plate for plate material is set within a range in which the screw engagement edge is displaced from the state positioned on the axial center extension line of the screw hole by a dimension corresponding to the axial radius of the maximum screw.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the side plate is provided with a claw for driving against the side surface of the plate material.

  Here, the mounting bracket uses a single elastic metal plate, with respect to the front edge of the side plate that is long in the vertical direction, the structural material front plate on one of the upper half and the lower half, and the plate material on the other The front plate is bent at a right angle so as to protrude on the opposite side, and the rear plate for the plate material is formed on the same side as the front plate for the structural material with respect to the upper half and the lower half at the rear edge of the side plate. The front plate for structural material and the front plate for plate material are bent so as to protrude on the same side as the front plate for construction, and the front surface of the structural material and the plate material is thereby flush with each other. To be finished.

  The plate rear plate has a vertical dimension shorter than that of the side plate. Specifically, the upper plate and the lower half of the side plate are provided on the same side as the front plate for the structural member. By making it a little longer vertically than the front plate for structural material, the longer part becomes the part facing the front plate for plate material, and the edge of this facing part side is the screw connection of the screw that penetrates the plate material It is a match.

  The front plate for structural material and the front plate for plate material are bent at a right angle with respect to the side plate, whereas the rear plate for plate material is bent in an inclined shape such that the free side edge slightly approaches the side plate, By bending the free side edge backward, this plate back plate becomes a clip part using the elasticity of the metal plate, making it easy to fit between the plate front plate and the back plate to the plate material, and at the same time against the plate material By elastically fitting externally, an error in the thickness of the plate material is absorbed.

  Further, the claw provided on the side plate is formed by cutting and raising a part of the side plate protruding on the same side as the front plate for the plate material, and the side plate is fixed to the side surface of the plate material by being fixed. The mounting bracket can be temporarily fixed, and the work of fixing the plate material between the structural materials can be performed efficiently.

  According to the mounting bracket of the present invention, the positional relationship between the screw engagement edges positioned above and below the plate rear plate and the screw holes provided in the plate front plate is screwed into the plate material from the screw holes of the plate front plate. Since the screw thread of the plate fixing screw that penetrates the plate engages with the screw engaging edge, the screw that penetrates the plate material is fastened to the plate material at the same time as the plate front plate and the plate material are fastened by screwing in the screw. By engaging the plate's screw engagement edge, the rear plate for the plate material is forcibly pulled forward, and the plate material is clamped from the front and rear by the front plate and the rear plate for the plate material. Even if there is, there is no gap between the plate rear plate and the plate member, and the clamping force of the plate member by the plate front plate and the rear plate can be used to improve the fixing strength of the plate member to the structural member.

  Further, the screw thread penetrating the plate material is engaged with the screw engagement edge of the plate rear plate, so that the two screws in the length direction are fixed to the plate front plate and the rear plate. By fastening the mounting bracket to the plate material, the support strength against the shearing force acting on the plate material fixing part of the screw is improved, and the fixing strength of the plate material that serves as the foundation for reinforcement when attaching handrails to the wall surface is secured sufficiently Can do.

  In addition, the mounting bracket does not require any bending at the work site when fixing the plate material, and the work efficiency for fixing the plate material is excellent, and the plate material is attracted to the front plate for the plate material by screws, so The plate material is finished on the same surface, and construction of the inner wall material can be performed without any trouble.
